Value of Inbound Link from PR=0 page?

Value of Inbound Link from PR=0 page?: "First, you must understand that there are different kinds of PageRank. There is the Google Directory PageRank and the Google Toolbar PageRank. They are both calculated differently. I will assume you are referring to the Google Toolbar since that is what most people think of when they refer to PageRank.

You actually answered your OWN question...

Quote:Originally Posted by ErgobobI understand that there is value to all links regardless of PR.

As you already stated, no page actually has a PageRank of ZERO. If a page has not been indexed, the Toolbar will show 'no data'. If it shows as being a '0 out of 10' in the Toolbar, it really means that the page has a value of less than 1.

Without going off on a very long detailed explanation of how PageRank is calculated and transferred, I'll just give the short version.

In theory, Google's algorithm assumes that every page on the Internet starts with a Value of 1 (or at least every page that they have indexed, which is somewhere around 12 billion right now). So, their system calculates a complete worldwide value of about 12 billion. They must disperse this PageRank to all pages based on linking structures. Being that it is a simultaneous equation, it really works like a pendulum that shifts fractions of PageRank from site to site, back and forth until the equation is as close to 'balanced' as is adequate to generate their Hub & Authority model.

If every page has an initial value of 1, part of that ranking is given up to a page it links to. If that page links back to the first one and nothing else, then it would be a wash and both pages would remain equal.

This is in theory. In reality, it is never that simple. You may have links from pages you don't even know about. Rem"
